Au/3DOM LaCoO3: High-performance catalysts for the oxidation of carbon monoxide and toluene

xAu/3DOM LaCoO3 (x = 1.54-7.63 wt%) are prepared using the PMMA-templating and PVA-protected reduction methods. The high Oads concentration, good low-temperature reducibility, and strong interaction between Au and 3DOM LaCoO3 are responsible for the excellent catalytic performance of 7.63Au/3DOM LaCoO3.
